Application filed April 24, 1923.

T 0 all whom 2'15 may concern:

Be 1t known that JOHN RA'rzEsBnnGnR,

a citizen of the United States, residing at Altoona, inthe county of Blair and State of Pennsylvania, has invented certain new and useful Improvements in Molds for Concrete Curbing, of which the following is a specification.

This invention relates to a mold for concrete curbing and has for its principal object to provide a device which is of such a construction as to enable the same to be readily assembled and disassembled without the use of complicated tools and further- 5 more. easily and quickly set up for use.

A still further object of the invention is to provide a mold which is of such a construction as to enable the same to be used for various forms of curbing such as formation of arcuate shaped sections as well as the straight sections.

A still further object is to provide a model of the above mentioned character, which is simple in construction, inexpensive, strong, durable and further well adapted for the purposes for which it is designated.

.Other objects and advantages of this invention will become apparent during the course of the following description.

so In the accompanying drawings forming a part of this specification and in which like numerals designate like parts throughout the same Figure 1 is a plan view of my mold showing the same in assembled position.

Figure 2 is a side elevation thereof. Figure3 is a vertical section taken on line 3-3 of Fig. 1.

Figure 4 is a vertical section taken on line Figure 5 is a detail perspective of one of the rods.

Figure 6 is a plan view of a modification showing the mold when used to form an arcuate-shaped curb.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numerals 1 and 2 designate the side plates of my mold and these plates maybe formed of rolled steel or sheet iron or ofany other suitable material. It being further understood that any other material may be used and I do notwish to limit myself to the particular material'used in conjunctionwith carrying ed to be received by the upper ends 8 of the Serial No. 634,254.

out the features of my invention. The outer faces of these side plates 1 and 2 are provided with a series of spaced eye bolts 3. These eye bolts 3 are countersunk in the outer faces of the plate and are arranged in. vertical spaced relation as more clearly shown in Fig. 2 of the drawings. Any number of these eye bolts 8 may be provided on the outer faces of the plates 1 and 2 respectively as desired. It will. be also noted that the outer faces of the plates 1 and 2 are provided with the enlarged eye bolts t which are. also arranged in vertical spaced relation with each other and are preferably arranged in pairs adjacent the outer ends of the plates and for the purpose hereinafter to be more fully described.

Adapted to extend through the vertically arranged eye bolts 3 on both of the outer faces of the plates 1 and 2 are the elongated rods 6. These elongated rods 6 are provided with suitable collars such as shown at 7 in the drawings and the collar 7 formed on each rod 6 is preferably formed thereon adjacent the upper ends thereof. The construction of this rod with the collar carried thereby is more fully shown in Fig. 5 of the drawings.

The purpose of providing the rods 6 with the collars 7 is to permit the longer portions of the rods 6 to extend through the vertical registering eye bolts 3 so that the collars 7 will rest-on the upper outer edges of the side plates 1 and 2 as more clearly shown in Fig. 3 of the drawings. The lower ends of the elongated rods 6 extend through the lowermost eye bolts 3 and terminating at a. point adjacent the lower edges of the side plates. The purpose of these rods 6 whereby their upper portions 8 extend above the top 9 ofthe side plates 1 and will be hereinafter more fully described.

- Adapted to extend transversely across the top of the side plates land. and also adapt elongated rods 6 are the clamping members 9. These clamping members 9 are formed of a suitable thickness of metal and are provided with apertures adjacent the outer ends thereof as shown at 10 in the drawings whereby the clamps 9 will. be seated on the collars 7 after the clamping members 9 have been placed over-the upper ends 8 of the elongated rods which extend through the ap-' ertures provided in the clamping members.

Any number of these clamping members and elongated rods may be used in connection with supporting the upper portions of the side plates 1 and 2 respectively whereby the same are held in proper alinement and are prevented from being forced outwardly when the concrete is poured between the side plates 1 and 2 during the formation of the curbing. 7

When it is desired to secure the side plates 1 and 2 in proper position in a suitable trench formed in the ground and to prevent the mold from collapsing or otherwise los ing its proper supporting position, I provide suitable braces 11. These braces 11 are formed of any suitable material and have their upper portions bent downwardly to provide hooks 12 which are adapted to fit within the enlarged eye bolts 4 provided in the side plates 1 and 2 adjacent the outer upper ends thereof and the lower ends of the braces 11. are provided with an aperture 13 for the purpose of receiving the anchoring member 14. This anchor member 14; is adapted to be driven into the ground whereby the side plates 1 and 2 will be held in roper vertical position in the trench and ldraces 11 on each side of the trench will furthermore aid in supporting the side plates in said vertical position while the same is being used for the purpose of forming a curb in the trench. If necessary an auxiliary brace may be associated with the lowermost enlarged eye bolt 4 in the manner similar to the use of the braces 11.

At one of the ends of each of the plates 1 and 2 respectively a transverse strip 15 and 16 respectively is adapted to be riveted to the outer faces of the ends of the respective plates 1 and 2 whereby the strip is adapted to have a portion thereof extending beyond the edges of the plates as more clearly shown in Fig. 1 of the drawings for the purpose of permitting a similar mold comprising inner plates similar to the plates 1 and 2 to be setin alinement with the plates 1 and 2 whereby a continuous mold is formed in order to permit the curbing to be formed in a continuous strip. As the sections will be of the same construction as the mold formed in the side plates 1 and 2 and the parts associated therewith in the manner heretofore described, it is not thought necessary to further go into detail as to the construction of the other sections. Any number of these sections may be used in order to perform the necessary functions in the formation of the concrete curbing and it will not require the use of a.- complicated number of parts or tools in order to set the form up in an assembled position.

In Fig. 6 of the drawings is shown a modification wherein the sections are of arcuate design and this form of mold is used when it is desired to form a curbing which is to extend around a corner or the like or any other suitable place where it is desired to use an arcuate shaped curb.

By furthermore permitting the collars T on the elongated rods 16 to rest upon the upper edges of the side plates 1 and 2 it will be noted that the clamping member 9 will be spaced from the upper edges of the plates so as to permit the person using the mold to have ready access to the top of the mold in order to obtain a smooth upper face on the curbing and thereby enable the person to readily use his tools in an efficient manner without in any way obstructing or removing the clamping means associated with the side plates.

It will thus be seen from the foregoing description that a mold for use in conjunction with forming concrete curbing has been provided wherein the necessity of employing a still form setter is obviated and an ordinary laborer may easily and accurately perform the same work as heretofore required the use of a skilled mechanic and the simplicity of the construction of my mold enables the same to be set up more easily and quickly than the molds now in use and furthermore considerable time and labor will be saved with the use of a mold of the above mentioned character.

From the foregoing description of the construction of my improved apparatus, it will be seen that I haveprovided a simple, inexpensive, and efficient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, without departing-from the spirit or sacrificingany of the principles of the invention.

What I claim as new and desire to secure by Letters Patent is 1. A mold of the class described compris- 11 ing a pair of plates provided with eye bolts on the outer faces thereof and arranged in vertical spaced relation, rods extending vertically through certain of said eye bolts, means on said rods for engagementwith the 11 upper outer edges of said plates, clamping means receivable on the upper ends of said rods and adapted to rest on said last mentioned means. and bracing elements associated with the other eye bolts at one end 1 and adapted to receive anchoring means in their opposite ends.

2. A mold of the class described comprising a pair of side plates provided'with eye bolts on the outer faces thereof and ar- 1 ranged in vertical spaced relation,-rods extending vertically through said eye bolts, collars formed on said rods adjacent the upper ends thereof and adapted to rest on the upper outer edges of said plates, clamping members receivable on the upper ends of said rods and seated on the upper faces of said collars, andbracing elements associated With said side plates.

3. A mold of the class described comprising a pair of side plates provided with eye bolts on the outer faces thereof arranged in vertical spaced relation, elongated-rods extending vertically through said eye bolts, collars formed on said rods adjacent the upper ends thereof and adapted to rest on the upper outer edges of said side plates, the upper ends of said rods extending above said side plates, clamping members receivable on the upper ends of opposed rods extending transversely across said side plates, said clamping members adapted to rest 011 the upper faces of said collars on said rods, and bracing elements associated with said side plates.

4. A mold of the class described comprising a pair of side plates provided with eye bolts countersunk in the outer faces thereof and arranged in vertical spaced relation, rods extending vertically through certain of said eye bolts, collars formed on said rods adjacent the upper ends thereof and adapted to rest on the upper outer edges of said side plates, clamping members extending transversely across the side plates and receivable on the upper ends of said rods and adapted to rest on the upper faces of said collars, bracing elements provided with hooks at their upper ends for engagement with certain of said eye bolts on said outer faces of said side plates, the lower ends of said braces provided with apertures for receiving anchoring means adapted to' be driven in the ground whereby said side plates are supported in a substantially vertical position.

In testimony whereof I affix my signature.

JOHN RATZESBERGER.
